Write about the causative agent for diarrhoea, its symptoms, modes of infection and the required preventive measures by the government during the outbreak.

Causative Agents

Vibrio cholerae causes cholera outbreaks; rotavirus, Escherichia coli, and Entamoeba histolytica also contribute significantly. Entamoeba histolytica causes amoebiasis, a common parasitic infection linked to poor water quality.

Surveillance and Treatment

The Integrated Disease Surveillance Programme1 (IDSP) facilitates early detection and notification of outbreaks; treatment involves oral rehydration salts and antibiotics like tetracycline for cholera. Andhra Pradesh strengthens district-level preparedness and confirms diagnoses through bacteriological stool examinations.

Sanitation and Coordination

Swachh Bharat Mission Gramin improves sanitation by providing latrines and safe drinking water; the State Disaster Response Fund (SDRF) aids resource mobilization during outbreaks. Coordination between central and state health bodies, supported by the National Disaster Management Authority, is crucial for effective response.

Environmental Factors and Data Gaps

Monsoon flooding and water stagnation in Andhra Pradesh contaminate water sources, causing seasonal spikes; limited granular data on disease burden hampers targeted interventions.

Way Forward

Expand water and sanitation infrastructure prioritizing vulnerable areas; enhance hygiene awareness through behaviour change campaigns involving local health workers and schools; improve surveillance by upgrading diagnostic facilities and data management for rapid outbreak response.
